<1> Displayed as or when occurring at drive power up. When one of the faults occurs after successfully starting the drive, the
display will show or .
<2> Occurs in models CIMR-A4A0930 and 4A1200.
<3> This function prevents continuous operation in reverse when using high frequency injection (n8-57 = 1) in the Advanced Open Loop Vector
Control mode for PM motors (A1-02 = 6) with a motor for which no motor code has been entered (it does not simply prevent reverse
operation). To quickly detect undesirable reverse operation, set L8-93, L8-94, and L8-95 to low values within range of erroneous detection.
<4> Fault trace (i.e., the fault history) is not kept when CPF00, CPF01, CPF06, CPF24, oFA00, oFb00, oFC00, Uv1, Uv2, and Uv3 occur.
